Bently Nevada 3300/20-13-02-01-00-00 Dual Thrust Position Monitor

Description

The Bently Nevada 3300/20-13-02-01-00-00 3300/20 Dual Thrust Position Monitor provides early detection of thrust bearing failure. It continuously measures and monitors two independent shaft axial position channels relative to the machine’s axial clearances. Ideally, axial probes are installed to directly monitor the thrust collar, ensuring accurate position measurement relative to the thrust bearing clearance.
